I bought a single version license because I almost never pay for games, because I almost never play them for more than a week or two before getting bored and moving on. This was true this time as well. If I could get the new version I might start it up again for another week or two, but it's certainly not worth it to me to get the lifetime one, and really I can't spare the time to play it that much anyway.
I agree 100% with this. It may *seem* like common sense to just shell 55 bucks and be done with it forever, but IMO:
$3 is like what you'd pay for a burger. It's really a tiny amount of money, and you can get a couple of weeks of gameplay, unlikely that a minor release will be ready in that time, and it's about what I agree is the most time I've been entertained by this game each time I play it.
$10 is still not much, but any "minor updates" are nice but unless there's some game-breaking bug I don't really see it worthwhile. You could say this is the "free maintenance" option. You still wouldn't have gotten the "upcoming" version with all these nifty upgrades.
$55, forever... it's a big bunch of money. IMO it's way too much for a small indy game like this. And if we want to be objective about it, it's the cost of at least 18 times the smaller one. You'd have to have updated the game at least 18 times for this to be worthwhile. If you count backwards, including every single minor version, including even like, 3.09a to 3.09b. But, you'd need to play this game continuously to get all of these. Most people I'd say would probably have skipped a few without even realizing they were out, because they didn't know they were out there. Even without paying, just trying the free version, I probably have only downloaded URW half a dozen times.
